PITTSBURGH (KDKA) — Police have arrested two men after a man who was mentally disabled was found dead in his Harrison Township home.

He moved into the house several months ago after living in a senior care facility.

Duff’s body was found showing significant signs of physical trauma, including cuts and bruising, which prompted the medical examiner’s office to label his death as suspicious.

Authorities say Duff had also been spray painted and doused with water.

Duff had also suffered a stroke several years ago and had limited mental capacity.

Authorities say Duff died sometime Sunday night or early Monday.

They also say his body was moved around the house repeatedly after he died.
